Lin Dan Khan finally attacked with his elite Chahar troops, and the first target was Chechen Khan in Mobei. The territory of Chechen Khan extends to the Erchis River in the east, Chahar Khan in the south, Tushetu Khan in the west, and Buryatia in the north.

Lin Dan Khan ordered an envoy to the Chechen Khan's garrison and demanded that the Chechen Khan submit to the Chahar Khan and pay tribute to the Chahar Khan every year. Chechen Khan Shuolei was willing to work, he was originally subordinate to Lin Dan Khan, and later after Lin Dan Khan converted, he never paid tribute. So the war between the two sides inevitably broke out.

Lin Dan Khan led with 3,000 Chahar cavalry, and was soon defeated by the cavalry of the Chechen Khan, who took advantage of the situation to cover the kill, but was met by the Jebe guards. A thousand muskets fired at the same time, and hundreds of Chechen Khan's cavalry were brought down, and with five bombardments in a row, the Chechen Khan's cavalry lost nearly 2,000 men. Lin Dan Khan took the opportunity to kill with a large army, and Chechen Khan was defeated.

Under the threat of such powerful firepower, Chechen Khan chose to submit very well and was willing to serve Lin Dan Khan as the co-ruler of Mongolia. And in the whole course of the battle, not a single one of the Jebel guards was injured, but each of them fired a firecracker, but they were given a share of 2,000 horses, 3,000 cattle, and 5,000 sheep. Wei Junru and his subordinates were very happy, such a battle was really too easy, with so little effort and so many captures.

After defeating Chechen Khan, Lin Dan Khan needed about three months to digest his capture, so Wei Junru proposed to Lin Dan Khan that he should take advantage of this rare leisure time to go to various places in Mobei to have a good time and take a look at the grassland scenery that is different from that of the Ming Dynasty.

Lin Dan Khan naturally responded to the Jebel Guards, and anyway, there had been no fighting in the past few months, so he asked people to take the Jebel Guards to walk around.

Wei Junru chose the northern part of the Chechen Khan's territory, and each person brought two horses and enough food, and began to train his troops. Although the Guards have strong firepower, the geographical environment of Mobei is very different from that of Monan after all, so Wei Junru needs to let the Jebe Guards adapt to the local environment more quickly.

And after the Chechen Khan was defeated by Lin Dan Khan, he sent people around to find out which Chahar army was the unit with the musket. The secrecy of the Chahars was slightly none, so the Chechen Khan soon learned of the existence of the Ming mercenaries.

In the process of Wei Junru leading the team to practice, he met an envoy sent by the Chechen Khan to contact feelings. Wei Junru did not hide it, so he told them about the mercenary army, and he smiled at the envoy's question about whether Chechen Khan could also hire Ming troops: "Of course we can, but we have been hired by Lin Dan Khan." However, if you need mercenaries, you can go to the Ming Dynasty and contact the Ming Staff Headquarters, but don't let the Ming court know. ”

After the envoy reported to the Chechen Khan, the Chechen Khan was overjoyed and secretly sent someone to contact Tushetu Khan and Zasaktu Khan and told them what Wei Junru had said. And it is recommended to send people to Daming with the other two Khans to see if they can hire the Ming army to come here to help them fight in order to deal with Lin Dan Khan's imminent invasion.

Tushetu Khan and Zasaktu Khan already knew that the main reason for the defeat of the Chechen Khan was the addition of the Ming mercenaries, so the two khans stepped up their alliance and deployed heavy troops on the border with the Chechen Khan to prevent the invasion of Lin Dan Khan. Now after getting the news, he sent someone to Daming to find a way.

The envoys of the three khans of Mobei came to Daming again in the name of tribute, and at the same time sent people to the general staff to inquire secretly. After Lu Xiangsheng received the report, he met with the visitors, and after hearing their intentions, he smiled and said: "What about the mercenaries, this official can be the master." But now that Lin Dan Khan has hired the army of the Ming Dynasty, if we also send mercenaries to the forces that oppose Lin Dan Khan, won't it be our own people to fight our own people at that time, I believe you can understand this. ”

The envoy was very disappointed, but after thinking about it, as long as he didn't fight the mercenaries under Lin Dan Khan's command, wouldn't it be fine? So he said: "Master Lu, what if we hire the Ming army, but don't clash with Lin Dan Khan, just to deal with the Oirats?" Wouldn't that be enough? ”

Lu Xiangsheng said: "You don't fight against Lin Dan Khan, but you want to fight against the Watt Thorns?" "Oirat is the tile spur, in fact, strictly speaking, the tile spur does not belong to Mongolia, the current Mongolia actually only refers to Monan and Mobei Mongolia.

The envoy said sadly: "With the help of the Great Tomorrow soldiers, how can we be Lin Dan Khan's opponents." If Lin Dan Khan persecuted too much, we would have only one way to move west. ”

Lu Xiangsheng said with a smile: "If you can really guarantee not to fight against the tribe where the current Ming mercenaries are located, we are willing to provide you with mercenaries." But then again, if the mercenaries find out that there are Ming mercenaries in the opponent's army, they will not participate in the battle. ”

The envoy said: "Please rest assured that Master Lu will definitely keep this in mind." ”

Lu Xiangsheng said: "We provide Lin Dan Khan with 5,000 mercenaries, and if the Mobei Three Khans need it, we can also provide 5,000 mercenaries, all the requirements are the same as those for Lin Dan Khan." I have an agreement here, you can take it back to your Khan to see, and if you can, in two months, our mercenaries will be ready. ”

The envoy returned to Mobei with the agreement, and Tushetu Khan read the agreement and said: "There is nothing wrong with this agreement, but if the mercenaries don't fight the mercenaries, how can we fight against Lin Dan Khan?" What do we want these mercenaries for, do we really use them to fight the thorns? ”

The messenger said: "Great Khan, at that time, the Ming people said that if the mercenaries found that there were Ming mercenaries in the opposing army, they would not participate in the battle, and there was a loophole in this sentence. If we put the mercenaries out first, or let them put a few firearms, then the Ming army in Lin Dan Khan's army will not fight with us, so what are we afraid of? ”

Tushetu Khan was overjoyed and said, "Did the Ming people really say that? Wouldn't we be able to use this rule so that Lin Dan Khan's mercenaries could not go to war? Quick, inform Zasaktu Khan that we also want mercenaries from the Ming Dynasty, and also tell the Chechen Khan that we hired troops from the Ming Dynasty in order to save him, and he will have to pay half of the hiring fee after the war. ”

The Three Khans of Mobei soon reached an agreement and immediately sent envoys to Beijing to discuss with Lu Xiangsheng about hiring Ming troops to participate in the war. When Lu Xiangsheng returned to the envoy, he had already selected a brave brigade commander Dai Bingyang, who also began to transfer manpower from the Guards, and after strict screening, formed the second brigade of the mercenary army of 5,000 men for emergency training. It took two months for the envoys to come and go, and the army had a lot of miscellaneous affairs, and by the time Dai Bingyang crossed the desert with the second brigade of mercenaries, Lin Dan Khan had already made a forced landing on Zasaktu Khan.
